Yosemite waterfall turns to ‘flowing lava’ in rare February spectacle caught on camera
On those days the setting sun illuminates one of the park’s lesser-known waterfalls so precisely that it resembles molten lava as it flows over the sheer granite face of the imposing El Capitan.

The lava-like appearance only happens with just the right alignment of the sun and the earth which creates the light.
Navy looks to Lockheed Martin, Atlas Elektronik for underwater robot mine hunters
At the heart of the Lockheed Martin airborne and shipboard mine neutralization systems is the Seafox neutralizer unmanned underwater vehicle (UUV) from Atlas Elektronik. The Seafox UUV is cued by mine detection and classification data previously gathered from a mine-countermeasures ship, aircraft, or UUV.
The neutralizer can operate autonomously by using onboard sensors to re-acquire the target automatically, or an AMNS operator can maneuver the vehicle manually to the target.
The Seafox UUV neutralizer uses real-time sonar data and video for guidance and target identification, and neutralizes the target by firing the system’s self-contained shaped explosive charge into or near the mine.
Seafox
Strangely, despite your second amendment rights to have arms to protect yourself this will probably not be allowed for personal ownership. Those living on the coasts are on your own. This Lockheed Martin/ Atlas Elektronik contract to build the Seafox is worth $45.6 million. So it is not like many of us could afford one anyway.
3D printer used to make bone-like material
It looks like bone. It feels like bone. For the most part, it acts like bone.
And it came off an inkjet printer.
Washington State University researchers have used a 3D printer to create a bone-like material and structure that can be used in orthopedic procedures, dental work and to deliver medicine for treating osteoporosis.Paired with actual bone, it acts as a scaffold for new bone to grow on and ultimately dissolves with no apparent ill effects.
The authors report on successful in vitro tests in the journal Dental Materials and say they’re already seeing promising results with in vivo tests on rats and rabbits. It’s possible that doctors will be able to custom order replacement bone tissue in a few years, said Susmita Bose, co-author and professor in WSU’s School of Mechanical and Materials Engineering.
“If a doctor has a CT scan of a defect, we can convert it to a CAD file and make the scaffold according to the defect,” Bose said.
After just a week in a medium with immature human bone cells, the scaffold was supporting a network of new bone cells. I wonder about the specifics of the use in dental work. Would they use the 3D scaffold to grow new enamel or would they be recreating a tooth or dentures for implant.
The research was funded with a $1.5 million grant from the National Institutes of Health. The video of the procedure – 3D printer used to make bone-like material (video)
It is every unfortunate that conservatives seem determined to gut Medicare – Lead by Rep. Paul Ryan (R-WI), GOP Not Giving Up On Medicare Privatization
Republicans want to turn Medicare into a subsidized private insurance structure and cut costs on the beneficiary side. This concept — dubbed “premium support” by backers and “vouchers” by critics — would end the coverage guarantee and give seniors a fixed amount to shop for insurance plans on a private exchange (similar to what the Affordable Care Act sets up). If the voucher is too small, tough luck; you’re on their own.
Very Orwellian to change the name of the procedure for shredding Medicare and Medicaid from the unpopular “vouchers” to “premium support”. Either way seniors and the disabled would be given a health care allowance and once that is used up – not to mention a deductible that would impose incredible hardships on those with low-income – you have to scramble to find some funds from who knows where to pay for everything over your allowance.
